Two years ago I blogged about a similar subject. I discussed the advantages of Internet Explorer (IE) over Mozilla and other web browsers in a corporate environment. I concluded that IE is by far the better choice. Recently we deployed about 250 new computers and so I considered this question again. Now, Firefox is the main rival of IE. The decision was not so easy this time, but IE won again in the end.
I am using Firefox myself for a quite while and I really like this web browser. However, when it comes to the question of switching to a new web browser in a corporate network, other arguments have to be considered.
